===== Missing Functionality =====

The canonical list of syscalls not yet supported by [[Linuxulator]] can be found at [[https://svnweb.freebsd.org/base/head/sys/amd64/linux/linux_dummy.c?view=markup|sys/amd64/linux/linux_dummy.c]].  The ones marked UNIMPLEMENTED() are not supposed to be ever supported, usually because they have been [[http://www.man7.org/linux/man-pages/man2/unimplemented.2.html|obsoleted upstream]].  The list below is somewhat stale.
